To describe categorical data... correct answer: Make a picture. Bar graphs or pie charts work well. Summarize the distribution with a table of counts or relative frequencies (percents) in each category. Compare distributions with plots side by side. Interpret Standard Deviation correct answer: Standard deviation measures spread by giving the "typical" or "average" distance that the observations (context) are away from their (context) mean. Outlier Rule correct answer: Upper Bound ...
